OPEN DATA
• NEW DATA SOURCES• QUALITY ASSURANCE• USE OF DATA• DATA AVAILABILITY• SHARE DATA
Korppoo et.al. (2015) Phosphorus and nitrogen species simulation with the modified VEMALA model at a catchment scale. – MODELLING WATER – NEW DATA
"Development of Vemala model by dividing nutrients into species. The system produces real-time short-term nutrient forecasts for Karjaanjoki using Maasää observations. Forecast and real time simulation data available for MMEA -Testbed."
WHY?- Based on customer people are intrested- Nitrogen (N) and phosphorus (P) both limiting the phytoplankton
growth- Model now desribes also NO3 ja PO4

National environment monitoring changes:a) In 1.1.2016 field work of the regional environment centers was outsourced.b) In 2017 new data and satellite products are launched in the MONITOR2020 project called ENVIBASE (7,3 Me)
WHY?- In order to combine multiple data source we have to uncertainty- To decided where to invest the uncertainty component are good to
know

"Complex event processing (CEP) is an emerging technology. Complex event processing (CEP) analyzes data streams and detects complicatedsituations in real-time.”
WHY?- emerging technology, helps to find data patterns- scalable, can combine various types of data- can use multiple data streams
OPEN DATA USAGE
RESULT: “With two variables, CO2 and VOC (volatile organic compounds), the first, distance-based model performs better with correct alarm rate of over 75 % and false alarm rate of under 10 %.

“Open data is easy to access anywhere and anytimeeven with a new EXCEL”
WHY?- reduce implementation time and cost &- increase product value/functionality
